Verwendung von amphiphilen Verbindungen als Verdickungsmittel in nichtwässrigen Medien und die so hergestellte Zusammensetzungen

摘要

Use of at least one amphiphilic cpd. (I) selected from N-oleoyl-N-methylglucamine (Ia), N-2-butyloxyloxycarbonyl-N-methyl-D-glucamine (Ib) or N-2-hexyldecyloxycarbonyl-N-methyl-D-glucamine (Ic) for thickening a non-aq. medium is new. Also claimed are: (i) a process for thickening a non aq. medium comprising dissolving at least one of (Ia)-(Ic) a non-aq. medium by heating at 70-90 degrees C then allowing to stand until thickening is complete; and (ii) an anhydrous compsn. comprising (Ia)-(Ic) in a non aq. medium. (I) is pref. present in an amt. of 0.1-20 (pref. 2-8) wt.% to maintain a discontinuous mesomorphic liq. crystal network. The non-aq. medium may consist of a fatty (pref. cetylic or stearic) alcohol, a solvent (e.g. octyldodecanol or decyl oleate) or an oily liq., e.g. a triglyceride, oil or gum or an active oil such as vitamin E or its derivs., solar filters, emollients e.g. perhydrosqualene or farnesol derivs.
